The newly minted Renault Nissan Mitsubishi Alliance, complete with a new logo, has laid out its ambitious growth and cost reduction plans for the next six years.

A major component of the new plans is to boost the use of common platforms. At the end of 2016, Renault and Nissan produced around two million cars per annum off two common modular platforms. By 2022, the companies hope to produce nine million cars annually off four common platforms.

One new platform will be for mid-size cars, and the other will be designed for electric vehicles with autonomous driving systems. The latter platform is expected to go into production in 2020 along with a new generation of electric motors and batteries.

In total, 12 new EVs will be launched by the companies by 2022. By then, battery costs are predicted to fall by 30 per cent, a 600km NEDC range will be possible, and a 15 minute quick charge will yield around 220km of extra driving.

Mitsubishi will start moving from its own unique platforms and engines to the alliance's shared ones from 2020, and its plug-in hybrid drivetrain technology will be adopted by the alliance for its larger vehicles.

The companies will also streamline their other powertrain offerings, with 22 of the alliance's 31 engines to be used throughout the organisation by 2022. These 22 engines will account of 75 per cent of the alliance's output. As of 2016, only 14 out of 38 engines were used across multiple brands.

As far as self-driving technology goes, the alliance plans on having a "highly autonomous" system, requiring continuous monitoring by the driver, available for highway use by 2018 and city use by 2020.

A more advanced highway system only needing occasional driver intervention will also be available in 2020, with a fully autonomous driver-free car pencilled in for 2022.

Under the new strategy, the three automakers hope to grow annual sales from over 10 million this year to 14 million by 2022. Revenues are forecast to grow from US$180 billion ($226 billion) in 2016 to US$240 billion ($300 billion) by 2022.

Synergies will reportedly be doubled from five billion euro ($7.5 billion) in 2016 to 10 billion euro ($15 billion).

Some of these cost savings will come from Mitsubishi's fuller integration in the alliance, with the three companies looking to share research and development costs, manufacturing facilities, and common platform utilisation.

In launching the new six-year plan, Carlos Ghosn, head of the alliance, said: "The Alliance has grown and performed with two members since 1999. With Alliance 2022, we will prove that we will grow and perform with three companies or more."
